How Does DeFi Work?
To understand What is DeFi? Beginner Guide 2026, you must understand three core components:

Smart contracts are self-executing programs stored on the blockchain. They automatically complete transactions when conditions are met.
For example:
- You deposit crypto
- The smart contract calculates interest
- You earn rewards automatically
No bank employee. No paperwork.
3. Crypto Wallets
To use DeFi, you need a crypto wallet such as:
- MetaMask
- Trust Wallet
These wallets connect you directly to DeFi platforms.

1. No Middlemen
